Scaffolds contendo uma fase, HAp, e duas fases cristalinas, C-HAp e β-TCP foram obtidos por impressão 3D e colagem, respectivamente, utilizando cristais de gesso como material de partida. Para ambos os casos, a transformação completa do precursor pode ser alcançada depois de 3 horas de síntese. Para os scaffolds bifásicos, a razão entre as fases constituintes (C- HAp e β-TCP) pode ser variada ajustando o tempo de síntese, ou seja, quanto maior for o tempo de reação, será favorecido a formação da β-TCP. Ademais, a presença não prevista do β-TCP confere um caráter inédito do resultado, visto que não há relatos anteriores da cristalização do β-TCP pela proposta descrita neste trabalho. Forma e dimensões não foram significativamente afetados durante o processamento e os scaffolds resultantes eram suficientemente fortes para suportar o manuseio e imersão em água (ou SBF). Os scaffolds desenvolveram uma camada de apatita sob sua superfície após 1 dia de imersão em SBF, o que sugerem que eles podem ser bioativos in vivo. A via de processamento proposta é eficaz para a fabricação de scaffolds bifásicos (C- HAp/β-TCP) a partir de corpos de prova de gesso.
